I think those were fake error messages and can be ignored. More details below.
Those error messages were due to "deletefile" operation in fileserver workload. When that operation is executed, a file in bigfileset is deleted. Since there is no createfile operation in the workload, sooner or later there will be no files left and thus deletefile operation will fail when picking up an existing file for deletion. The code didn't handle the failure well and thus you saw the error messages. You can verify this by running other workloads(ie., varmail, copyfiles, etc.), they don't have such an issue.
